Embodiment
[0017] A method for making a silver nanoarray, comprising the steps of:
[0018] 2) The design of the positioning template, through the design of the template, determine the size and quantity of the micro-area, each micro-area must be an independent area;
[0019] 2) According to the number and size of the designed templates in step 1), use a laser direct writing machine to make a template mask, and then select a glass sheet as the substrate material, and deposit the cleaned glass sheet through high vacuum resistance evaporation on it. Deposit a chromium layer with a thickness of 250-300 nm on the surface; make the designed pattern on the glass substrate by photolithography, and edit the number;
[0020] 3) Put the prepared positioning template in step 2) into the washing solution made of concentrated sulfuric acid and hydrogen peroxide. The ratio of concentrated sulfuric acid and hydrogen peroxide is 3:1, heat to 80°C, and soak for 60 minutes;
[0021] 4) Rinse the positioni...
